Email Composer
Use this skill for any email-writing task — from a single cold outreach to a full nurture sequence.
1. Discovery Questions
Before writing, identify (or infer sensible defaults for):
| Question | Why it matters |
|---|
| Who is the sender? | Determines voice, credibility signals |
| Who is the recipient? | Tone, familiarity, pain points |
| What is the goal of this email? | Call to action, conversion outcome |
| What is the relationship? (cold / warm / existing customer) | Level of directness and formality |
| What tone? (professional / friendly / urgent / casual) | Writing register |
| Is there a specific CTA? | What action the reader should take |
| Has the recipient received emails before? | Follow-up vs first contact |
If not provided, write with sensible defaults and offer variants.
2. Email Types & Strategies
Cold Outreach
Goal: Get a meeting, demo, or response from someone who doesn't know you.
Structure:
- Hook (1 sentence) — specific to them, not generic
- Relevance (1-2 sentences) — why you're reaching out to THEM specifically
- Value (1-2 sentences) — what's in it for them
- CTA (1 sentence) — single, low-friction ask (15-min call, not "sign up")
- Sign-off — name, title, company
Rules:
- Subject line: specific, not salesy (avoid ALL CAPS, "!", "free")
- Never start with "I" or "My name is"
- One CTA only — multiple asks kill response rates
- Under 150 words if possible
- Personalization token: reference their company, role, or recent work
Follow-Up
Goal: Re-engage someone who didn't respond.
Rules:
- Reference previous email in first sentence
- Add new value or context — don't just say "following up"
- Shorter than the original
- Max 2-3 follow-ups in a sequence before stopping
- Space: 3-5 days after first, 5-7 days after second
Follow-up sequence spacing:
- Email 1 (initial) → wait 3-5 days
- Email 2 (follow-up 1) → wait 5-7 days
- Email 3 (follow-up 2) → wait 7-10 days
- Email 4 (break-up) → "Is this still relevant? Happy to close out if not."
Sales / Demo Request
Goal: Book a demo or qualify interest.
Additional rules:
- Mention a specific pain point relevant to their industry/role
- Include one social proof element (customer name, metric, result)
- Make the CTA a question: "Would a quick 15-min call make sense this week?"
Customer Onboarding
Goal: Welcome a new user/customer and drive activation.
Structure:
- Warm welcome (acknowledge their decision)
- What to do FIRST (single next action, link to it)
- Quick win (what they can accomplish in under 5 minutes)
- Support link or reply invitation
- Sign-off from a real person (not "The Team")
Transactional (confirmation, receipt, alert)
- Subject: clear and specific ("Your order #1234 is confirmed")
- Body: 3 sentences max — confirmation, key details, next step
- No sales content in the same email
3. Subject Line Rules
What works:
- Specific > Generic: "Quick question about [CompanyName]'s onboarding" > "Partnership opportunity"
- Short (4-7 words ideal for mobile preview)
- Creates curiosity without being clickbait
- Personalization in subject: outperforms generic by ~30%
What to avoid:
- "Following up" (overused, vague)
- ALL CAPS or excessive exclamation marks
- "FREE", "Limited time", "Act now" (spam triggers)
- Questions that can be answered with "no"
- Emojis (context-dependent; use sparingly for B2C, rarely for B2B)
Subject line formula templates:
[Specific observation about them] — quick thought[Problem they have] → [hint at solution][Mutual connection/company] → reaching outRe: [Topic they care about] (for warm follow-ups)
4. Tone Calibration
| Tone | When to use | Signals |
|---|
| Formal | Enterprise, C-suite, legal, finance | Full sentences, no contractions, proper salutation |
| Professional | Standard B2B | Contractions ok, friendly but structured |
| Friendly | SMB, startups, peers | Conversational, "Hey [Name]", light humor ok |
| Casual | Existing customers, close contacts | First name, short sentences, emojis ok |
| Urgent | Time-sensitive offers, alerts | Short, action-forward, deadline stated |
5. CTA Design
A strong CTA:
- Is ONE action only
- Is specific ("Book a 15-min slot here: [link]" not "Let me know if interested")
- Is low-friction (not "sign up", "buy", "commit")
- Has a built-in reason to act now (optional: "I have 3 spots open this week")
CTA formulas by goal:
- Meeting: "Do you have 15 minutes [day] or [day] this week?"
- Response: "Does this resonate, or am I off-base?"
- Demo: "Want me to show you how [outcome] in 20 minutes?"
- Breakup: "Should I close out this thread?"
6. Output Format
Always deliver:
- Subject line — with 2 alternatives labeled (A, B, C)
- Body — full email, ready to paste
- Personalization notes — where to fill in [brackets] and what to put there
- Tone rating — brief note on the tone used and why
- Variants (optional) — if requested, shorter/longer/different CTA version
7. Email Sequence Builder
For multi-email sequences, output as a table first:
| # | Timing | Goal | Subject preview | Key hook |
|---|
| 1 | Day 0 | First contact | ... | ... |
| 2 | Day 4 | Follow-up | ... | ... |
| 3 | Day 10 | Break-up | ... | ... |
Then write each email in full below the table.
